  • Communication disorders caused by Right Hemisphere Damage manifests different symptom with that of left, and studies concerning language evaluation and intervention have not been actively investigated because they are either mild or difficult to discern through the aphasic assessment targeted to left hemisphere damage patients. This study analyzes domestic and international RHD group study trends in last 10 years for the purpose of examining the trends regarding directions of RHD group communication disorders and intervention. 75 thesis were analyzed(13 domestic and 62 international) after classifying them into two categories, study type and research area. Regarding research type, both domestic and international studies primarily comprised characteristic comparison. As for the research area, both studies mainly investigated on extra-linguistic ability. While international studies frequently investigated the development and suitability of evaluation instrument as well as RHD group's activities of daily life. Domestic studies have shown limited scopes of research. Therefore, it seems that more attention should henceforth be payed to RHD patients in domestic level, and in-depth studies of diverse subjects should be conducted as well.

  • Cognitive-communicative disorders after traumatic brain injury(TBI) and right hemisphere damage(RHD) are different from other neurological disorders in nature. Therefore, it is not desirable to use aphasia tests in evaluating individuals with TBI or RHD. The aim of this study is to review assessment protocols on TBI and RHD, and literature related with them. As a result, it is recommended that individuals with TBI be examined in scope of the cognition including attention, memory, organization, reasoning, as well as the functional communication. Similarly, it is useful to consider high-order language related to various cognitive domains in assessing cognitive-communicative ability after RHD. In conclusion, we need to focus on the overall cognitive-communicative domains in an evaluative process of TBI and RHD. Furthermore, it is necessary to develop multiple items for individuals with cognitivecommunicative disorders for the purpose of differentiating these heterogeneous groups from other neurological disorders such as aphasia, and of making good use of them as a therapeutic manual.

  • This study was intended to analyze how well people with right hemisphere damage can understand Korean proverbs. This study used a between-subject design and within-subjects design where all subjects participate in the three experiments for 10 hospitalized patients of whose average age is 66.1 years old and 10 normal adults in the same age range. Experiment 1 was to make up Korean proverb related stories and suggest it in written, Experiment II was to suggest a picture presenting a Korean proverb and the proverb itself directly, and Experiment III was to make up a story related to a Korean proverb and tell it auditory. Five Korea proverbs were used for each experiment; 15 in total. The results were as follows: First, there was a significant difference in understanding of Korean proverbs between normal adults and people with right hemisphere damage. Second, there was no significant difference of understanding between them by stimulating methods to suggest Korean proverbs. Third, people with right hemisphere damage had a tendency to interpret Korean proverbs literally as a total wrong reaction was composed of 55.36%. Considering the above the results, it can be said that people with right hemisphere damage have less understanding of Korean proverbs than normal adults, which is not affected by a way of or a condition of suggesting Korean proverbs in people with RHD, and they are inclined to make literal interpretation of Korean proverbs as they are.

  • Objective: The purpose of this study was to examine the characteristics of prosody of ambiguous sentences in patients with right hemisphere damage(RHD). Methods: Sentences with each word prosodically focused were used to investigate. Several acoustic parameters such as intensity, F0, and duration were measured to identify characteristics of prosody in patients with lesions in the right hemisphere and normal controls. All speech samples were recorded using the Praat 4.3.14 software. Data were analyzed with the independent sample t-test using SPSS 18.0. Results: The results of this study are as follows: First, intensity of the first syllable of the focus word was different between the two groups in several sentences. Second, F0 was different between the two groups in all sentences. Third, duration was different between the groups in several sentences. Accordingly, prosody were varied and values of acoustic parameters differed due to the focus of utterance. The group with right hemisphere damage showed restricted prosody. Conclusions: Intensity, duration, and F0 are all used as elements of prosody in emphasizing structural and pragmatic meaning, but according to the focus, strength and duration were related to F0. In contrast, F0 has a significant linguistic difference, but there was a significant difference between the RHD and normal people, so F0 can be a discriminatory factor of rhyme evaluation of the right hemisphere damaged and it is necessary to accumulate more strong evidence through future research.

  • This study examined the characteristics of linguistic prosody in terms of cerebral lateralization in three groups of 9 healthy speakers and 14 speakers with a history of stroke (7 with left hemisphere damage (LHD), 7 with right hemisphere damage (RHD)). Specifically, prosodic characteristics related to speech rate, duration, pitch, and intensity were examined in three types of interrogative sentences (wh-questions, yes-no questions, alternative questions) with auditory perceptual evaluation. As a result, the statistically significant key variables showed flaws in production of the linguistic prosody in the speakers with LHD. The statistically significant variables were more insufficiently produced for wh-questions than for yes-no and alternative questions. This trend was particularly noticeable in variables related to pitch and speech rate. This result suggests that when Korean speakers process linguistic prosody, such as that of lexico-semantic and syntactic information in interrogative sentences, the left hemisphere seems to be superior to the right hemisphere.
